Hello all,

How do I setup gcc library path (LD_LIBRARY_PATH) for bjam?

For example I get this error when using bjam:

lcaminiti_at_lcaminiti-PORTEGE-R700:~/sandbox/boost-sandbox-local/libs/local/example$
bjam -q profile_boost_local toolset=gcc
...patience...
...found 790 targets...
...updating 2 targets...

-Wl,--start-group "bin/gcc-4.5.1/debug/profile_boost_local.o"
-Wl,-Bstatic  -Wl,-Bdynamic  -Wl,--end-group -g

...failed gcc.link bin/gcc-4.5.1/debug/profile_boost_local...

...updated 1 target...

But I can tell bjam to add -L and -l options as in the following it would work:

lcaminiti_at_lcaminiti-PORTEGE-R700:~/sandbox/boost-sandbox-local/libs/local/example$
g++ -o "bin/gcc-4.5.1/debug/profile_boost_local" -Wl,--start-group
"bin/gcc-4.5.1/debug/profile_boost_local.o"  -Wl,-Bstatic
-Wl,-Bdynamic  -Wl,--end-group -g
-L/home/lcaminiti/sandbox/boost-trunk/stage/lib -lboost_chrono
-lboost_system

Thank you.
